The existing structure at this location was a twin corrugated metal pipe culvert with each barrel measuring nine feet in diameter. The seams of the existing pipe culverts were buckling in some locations along with extensive corrosion along the flowline of the pipes. This was coupled with the existing pipes being hydraulically undersized for the location.  

The scope of the project involved replacement of the twin CMP culvert structure with a triple barrel 12-foot by 12-foot cast in place reinforced concrete box culvert. The new culvert is 101 feet out to out of headwalls and is skewed 25 degrees. HEI completed the field surveying, hydraulic analysis, Preliminary Bridge Design & Hydraulic Report, environmental coordination, utility coordination, structure design, and approach roadway design. The construction of this culvert utilized Township Bridge Program and REBUILD Illinois funding.
